what kind of an impact could an attack on the new york stock exchange have on the economy? joining me now is former nsa official colonel cedric layton. welcome back to the show. >> my pleasure, melissa. melissa: on the positive side reaction to today's hearing sort of across the board was that this certainly seemed up front, more professional, more prepared than the parade of jokers we saw coming out to testify on behalf of the irs or any other hearings. this had much more official, much more researched feel tooit, would you agree with that? >> oh, absolutely and when you look at the relationship nsa has had with the congressional oveesight committee such as the house committee where this hearing was today and the senate intelligence committee, i'll tell you from my personal experience as well as what i saw today it was absolutely the mos% professional hearing. it was very much to the point. it got a lost questions answered and, really an example how these kind of activities can be examined through congressional oversight and something i think americans are hopefully proud
